agricultural implements, and particularly to combined harrows and cultivators.

An object of this invention is the provision of a combined harrow'and cultivator pulverizing blades and'plows being adjustable so that either a ridge or a furrow may be formed between the rows.

Another object of this invention is the provision of an agricultural implement of this character in the frame of which knife heads are pivotally mounted to'which longitudinally'extending cutting blades are connected,'means being provided to support the knife heads in adjusted position so that the blades will engage in the ground to the desired depth.

With these and other objects in" view, as {will become'more fully apparent as the description proceeds, my invention consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevational view of my device; Fig. 2 is a top plan view thereof; Fig. 3 is a sectional view on the line 3-3 of Fig. 1; Fig. 4 is a detail view'showing the mounting of one of the plowbeams in the frame; Fig. 5 is a sectional view on the line 5-5 of Fig. 4; Fig. 6 is a fragmentary bottom plan view of one of the cutting blade supporting plates; and Fig. 7 is a detail view showing the manner of connecting one of the blades to one of the plates.

Referring more particularly to the drawing, my improved implement includes a frame which consists of a center bar 1 and 59 two parallel side bars 2, the ends of which are bent inwardly'and secured to the side faces ofthe'center bar, the inturned ends 3 forming the end portions of theframe. The ends of the center "bar project forwardly end of the center barbeing turned upwardly This invention relates to improvements in,

which includes a frame upon which plows and pulverizing blades are supported, the

and rearwardly of the frame, the forward as at4 to provide a support for any, suitable animal attaching means. Secured at their ends to the side bars -2 and center bar 1 intermediate of the ends of the frame are transversely extending brace bars 5, and connected at their forward ends to the brace bars 5 and at their rear ends to the rear in-, turned ends, 3 of the side bars are plow supporting beams 6 through the rear ends of Patented June 8, 1 915.

which pivot pins 7 are passed upon which plow standards 8 are pivotally mounted.

[Pivotally mounted on the rearwardly projecting end of the center bar 1 and also on the sidebars 2 forwardly of the standards 8 mounte'd on the brace bars 5, are similar plow standards 8, each of the standards having a forwardly and downwardly curved upper end Sin which a series of openings 10 is formed, whereby bolts orother suitable fastening devices may be passed through the openings 10 and through openings in the bars upon which the standards are mounted, whereby the standards may be secured in any desired adjusted position with relation to the frame.

The side bars 2 wardly ofthe brace bars 5 are provided with transversely alined openings 11 through which a supporting rod 12 is engaged, and

. mounted on the supporting rod on opposite sides of the center bar 1 are knife supporting plates 18, which are substantially U- shaped, the inner ends 14: of the plates being of relatively greater length than the outer ends 15 thereof. Formed in each vertically disposed end of the plates is a Vertical series of openings 16,. the supporting rod 12 being adapted for engagement through the 'alined openings 11 and through one of the openings of each upturned end of the plates 13 to pivot-ally connect the plates to'the frame. Formed in the body, portion of each plate adjacent its forward edge is a longitudinally extending series of openings 17, through which the upper ends of supporting'bolts 18 are passed, the looped forward ends 19 of rearwardly extending cutting blades 20 being engaged around the bolts, the blades 20 being secured to thebolts by the nuts 21 which are threadedly engaged on the upper ends of the bolts and bear and the center bar 1 forto the underfa'c'es of the plates 13, the oppo- 11in the sidebars and center bar of the frame, and through one of the openings in the outer end'of each supporting plate and 1 through one of the lowermost Openings in siteedges of the plates -22'being closelyengaged" against the opposed faces of the 'ad-- jacentblades; V

' Securedat their forward ends to thefront inturned ends of the side bars 2 and at their rear ends to the brace bars 5' on oppo site sides of the center bar are upwardly bowed rack bars 23 which are provided adjacenttheir rearends,- with longitudinally extending slots 24, the walls of the slots being formedwith rack teeth 25. Project- I the lockingpl atesbeing, reduced asat 29 and ing through the slots 24 in the rack bars are e the. -levers=-26, the lower ends of which are thelreduced; ends-of the plates being extended below the sleeves 27 for engagement through the slots24: forwardly of the levers,

I v the-side edges of the reduced ends 29being adapted for engagement with the rack teeth to hold: the levers in adjusted position. The upper ends I of the locking plates 28 are "curved forwardly and downwardly to pro vide finger pieces '30. whereby the sleeves may be readily raised to disengage the looking ends 29; of the plates from the. rack teeth so that the levers may be adjusted to regulate the depth to which the cutting I blades jare engaged in the ground.

Connected at their lower ends to the .cen-

terbar l rearwardly of the brace bars 5 are rearwardly inclined diverging handles 31, thehandles: being secured in their inclined 4 positions by suitable braces. 32 which are secured at their lower ends to the opposite faces ofthe center bar, and at their upper ends to the handles intermediate of their ends, the handles being further supported by other braces 33, which are connected at their lower ends to the inturned rear ends of theside bars 2, and at their upper ends to, the handles adjacent the upper ends of the same i In the practical use of my implement, the frame isdrawn overthe ground by an animal in the, ordinary way, the same being guided by anl operator who grasps the handles-31, and when the implement is desired for use, as a harrow, the knife supporting-plates13aresupported in the frame so that an of the blades 20' are; arranged to engage the ground at the same depth, the plow; standards 8 being adjusted withthe plows- .carried thereby engaging in the like, thesupporting rod 12 is-removed so that the plateslamaybe "arranged with their inner endsv disposed ,higher than the outer side of the frame.

rod is passed through the falined openings theinner end of each supporting p late,the plates are carried by the-framein such'position that the blades in the center of the frame are raised above the blades at the With the cutting blades in this positiom'the plow: standard on the rear of the center beam and the standard supported on the beams 5 are adjusted so that the plows carried thereby are arranged above the plows supported on the beams carried by theside bars 2, so that-as the implement is drawn over the ground a ridge is left below the longitudinal centerof the frame. lVhen it isdesired to forms, furrow between the rows, the rod 12 is removed so that the same may be passed through one of the upper openings in the vertical'series formed in the inner upstandingend of each plate 13,.wh'ereby the blades 20adjacent the center of the frame aredisposed below the bladesadjacent'the sides of the frame. The plow standards .8 are then adjusted so that the plows carried by the standards, on'the center bar and on the beams 6 are arranged below the standards carried by the sidebars so that as the machine is .drawnover the ground a longitudinal furrow is forinedbetween the rows. Thedistance to which the blades 2 0 engage in the groundto pulverize the same may be readily adjusted without disengagement of the supporting rod '12, it being merely necessary in performing this adjustment, toraise the sleeves 27 on the ends of the blades to the desired position with relation to the frame, whereupon the sleeves may be released so that the locking ends 29 of the plates 28 may again engage the rack teeth to hold the in adjusted position.

Having thus fully described my invention, what I desire to claim and secureby Letters Patent is: 7
